Breja: Honestly, I don't like this trailerm uch at all. It just seem rather boring. "Hey, look, it's dark everywhere and there's a guy in ridiculous armor and he fights some rock monsters and it's all super serious and morose as shit and... that's sort of all we've got. Awesome, right?"
My favourite cinematic trailer for WoW was the very first one. It just felt right- it promised this vast, beautiful and magical world to explore and have adventures in. I even liked the one for Mists of Pandaria way more than this one. At least it was funny, and again at the end it promised something new and fresh and interesting to see (not enoughto have me play it, but still).This one shows absolutely nothing that would make me feel like going back to WoW might be a good idea.
Klumpen0815: My favourite teaser from the Warcraft universe was the first one of Warcraft 3 from 1999:
https://www.youtube.com/watch?v=LWsYl_8Y3v4 It's not overloaded with shiny technical stuff, the orc doesn't look as physically impossible when it comes to the mass / agility ratio as they do today, the athmosphere is dark and grim... it's still the old and epic Blizzard. Not as brutal as the cinematics in Warcraft 2, but I'm fine with that and the graphical quality is very good if you consider, that it is 16 years old.
The Arthas cinematics in Warcraft 3 are the best cinematics in the game.
